Dear readers,
Spring has arrived – a season of renewal and growth, and one that invites reflection as much as anticipation. With this April issue, we look ahead with cautious optimism. While the green hydrogen sector continues to move forward, recent developments suggest we are entering a period of recalibration. Headlines about delayed projects and market consolidation may raise eyebrows, but they are also signs of an industry maturing – strengthening its foundation for more sustainable progress.
At the forefront of this evolution stands our cover story, which introduces Rely – a joint venture between Technip Energies and John Cockerill. Formed in late 2023, Rely is not just another entrant in the electrolyser space. It represents a strategic shift towards modularity, performance guarantees, and productisation in green hydrogen plant delivery. By offering integrated, end-to-end solutions, Rely reduces the complexity typically associated with large-scale hydrogen projects. In an industry now defined by performance and delivery – not merely ambition – Rely’ s approach is especially timely.
This feature sits alongside two articles that provide valuable context on the shifting landscape of electrolyser manufacturing. One, authored by Stephen B. Harrison, examines how consolidation is reshaping the sector – suggesting that only those companies with robust technology, strong commercial strategies, and deep-pocketed backers will remain viable. The other offers an overview of the latest vendor ranking by Guidehouse Insights, which assesses the most prominent electrolyser manufacturers based on market strategy and commercial execution – helping readers understand who is best positioned to navigate the current market turbulence.
Also in this issue, we explore the technical and economic challenges of powering direct reduced iron( DRI) processes with green hydrogen. A detailed analysis from Siemens Energy presents modelling based on real-world weather data, renewable energy configurations, and battery storage – offering a valuable roadmap for decarbonising steel production. Further along the value chain, a case study on the OAL project in Germany describes how a dual-purpose offshore pipeline was fast-tracked to provide immediate LNG import capacity while being designed to transport hydrogen in the future – a compelling example of infrastructure planning aligned with long-term energy transition goals.
Finally, I am delighted to draw your attention to the Hydrogen Tech World Conference 2025, taking place on 13 – 14 May in Düsseldorf, Germany. This focused event is the only one of its kind dedicated entirely to the integration of electrolysers into industrial operations. With contributions from leading voices in EPC, system integration, and hard-to-abate sectors, the conference will explore the technical, economic, and practical challenges of scaling up hydrogen solutions through in-depth insights and real-world case studies. You will find the full programme at the end of this issue – I hope it will inspire you to join us in Düsseldorf.
Until then, I wish you an insightful and energising read.
